Lenovo Yoga randomly going to Sleep Mode on Windows 10

Hello,

I am experiencing a very frustrating thing. My Lenovo Yoga laptop is falling asleep randomly. When I move from my device for more than 5 minutes, or simply do something else without touching the mouse or the keyboard, it falls into a coma. Sometimes, in longer periods of inactivity (e.g. 45 minutes) it completely shuts down. Since forever, my energy settings are differently set up (to fall asleep after 2 hours). Still, nothing helps. Also, it all happens either in full battery mode or in the charging mode...

I am looking forward to hearing any suggestions about how to fix this - I am desperate. :-(

Thank you!

Do you know what is causing this issue?

    One thing I see often is that there's many types of power management - and if one of these settings is wrong it can be hard to know which one.

    There's actually 5 difference places to check for power and monitor timeout settings, and usually just one of these needs to be edited:

    1. Right-click Desktop > Personalize > Themes > Screensaver link

    Even if you don't use a screensaver, the minutes setting on this dialog is used to lock or blank your screen.  So even if you have this set to "none", you still have to make sure the checkbox is off or else your screen will still blank.

    ⚠ This is by far the most popular issue I see. 2. Control Panel > Power Options > Change when to turn off the display 3. Control Panel > Power Options > Change when the computer sleeps 4. Settings App > Lock Screen Settings 5. Settings App > Accounts > Sign in optionsHere you'll want to make sure the "require sign in" drop down at the top is set properly.

    It's probably number 1, because even if your screensaver is set to "none", the timer on that page still applies. So it will time out after that time and go to the lock screen, which then also goes to sleep or hibernate.

    So again, screensaver is the most likely cause, especially since you already checked the actual power settings.  And again, the screensaver option applies even if you never had or never used a screensaver.

    You might inquire at https://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/YOGA-SERIES/YOGA-3-PRO-1370-LAPTOP-LENOVO

    I suggest using the "Update Your System" tool on the right side of the page first.

    HI, Shawn,

    It shuts down with CPU as planned by my settings (firstly it was one hour but now I intentionally set to 120 min). For everything under 1 hour of inactivity it goes to sleep mode, because I have to log in every time .. :( Since this issue is present for a couple of weeks now, I can't tell if it is only sleeping, I think it went down completely a few times, in a way that nothing works, and nothing of my current work being saved...

    I appreciate your help!

    Are you sure it's going to sleep, or is it possible that only some other thing is happening (like only the monitor going black, but the CPU stays active)?
